Not trying to be an ass, but how would Summit know what bearings you need? You need to know the crank journal size and the size of the rod openings. They can give you stock bearings that should work if the engine has never been touched and has all original parts, but that is all they can do. It is required that a plastigauge check be done of the installed bearings even if everything is stock to verify clearances, starting with the crank bearings. Part goes on with plastigauge installed, torqued, plastigauge checked, if good, assembly lube, then next bearing until all are installed. A little time and some cheap plastic strips will save you from the risk of collecting engine parts off the road down the line.
